% Hysteresis threshold.
This only works for grayscale images. Has a built-in demo using
CalibrationPattern.jpg.

Form:
HysteresisThreshold;
p = HysteresisThreshold( iN, e0K, tauH, tauL )
--------------------------------------------------------------------------
------
Inputs
------
iN (:,:) Edge strength
e0K (:,:) Orientation of the edge normal index
tauH (1,1) Upper threshold
tauL (1,1) Lower threshold
-------
Outputs
-------
p {} List of points
